I really was not sure what equation I should use because I didnt really know what the impulse was. I chose f*"change in"t=mvf-mvi.
2.7 N*s= (.24kg)(0m/s)-(.24kg)(v)
I got v=-11.25m/s. I know this was wrong, but Im not sure which equation I was supposed to use or if I entered the information correctly in to the equation. Any help would greatly be appreciated.
